Description

TECHNICAL FIELD

[0001] The utility model belongs to gas dryer technical field, concretely relates to a zero gas consumption compression heat regenerative adsorption dryer. BACKGROUND

[0002] The compressed air of air compressor outlet has very high relative humidity, which is inevitable in the process of generating compressed air. In order to avoid the harm of water in gas to gas system equipment, the water content must be limited in a certain range through the dryer.

[0003] The compression heat regenerative adsorption dryer regenerates the saturated wet desiccant by using the originally dissipated compression heat, has the electricity saving advantage compared with the blast auxiliary heating regeneration in many working conditions, and meets the energy saving and emission reduction policy. But most of the compression heat regenerative adsorption dryers currently directly contact the adsorbent with the hot compressed air discharged by the air compressor for regeneration, and the defects are as follows: 1. for the centrifugal air compressor, the hot compressed air discharged has low temperature and high humidity, and the regeneration effect of the adsorbent is poor, and additional heat input is needed; 2. the hot compressed air needs to pass through the heat exchanger, the separator and the valve to enter another adsorption tower for drying treatment, and then is sent to the rear end, so that the process pressure loss is large, and the energy consumption is indirectly increased; 3. the oil in the hot compressed air can reduce the adsorption drying capacity and shorten the service life of the desiccant, so it is only suitable for oil-free air compressors.

[0004] Although individual does not directly contact, but uses the compressed air product gas after drying to cool the adsorbent, has gas consumption, and the production energy consumption cost of the product gas is very high, and can even exceed the saved electric energy. SUMMARY

[0010] The compressed air is cooled to the required temperature through the second heat exchanger, and then is introduced into the gas-water separator.

[0011] The compressed air is cooled through the second heat exchanger, and then is introduced into the gas-water separator.

[0012] The compressed air is dried through the adsorption tank, and then is discharged from the top of the adsorption tank.
